Equivalent focal length on different cameras#
Field of view and depth-of-field equivalence when this lens is used on bodies with different sensor sizes (natively or via an adapter).
| Camera format | At 15 mm | At 26 mm | At 45 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| APS-C | 22 mm · 86° | 39 mm · 57° | 68 mm · 35° | f/5.2 |
| APS-C (Canon) | 24 mm · 84° | 42 mm · 55° | 72 mm · 33° | f/5.6 |
| Micro Four Thirds | 30 mm · 72° | 52 mm · 45° | 90 mm · 27° | f/7.0 |
Depth of field & background blur#
Computed on its native APS-C format (CoC 20 µm). “Blur @2 m” is the size of an out-of-focus point at infinity, as a percentage of frame width, with the subject at 2 m — a simple bokeh index. Full table: 16 mm f/4 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 15 mm | f/3.5 | 65.8 cm | 3.80 m | ∞ | ∞ | 3.30 m | 0.1% |
| 15 mm | f/4 | 77.6 cm | 5.27 m | ∞ | ∞ | 2.89 m | 0.1% |
| 15 mm | f/8 | 2.58 m | ∞ | ∞ | ∞ | 1.45 m | 0.1% |
| 26 mm | f/3.5 | 19.9 cm | 83.3 cm | 6.75 m | ∞ | 9.90 m | 0.4% |
| 26 mm | f/4 | 22.8 cm | 96.4 cm | 8.61 m | ∞ | 8.67 m | 0.4% |
| 26 mm | f/8 | 47.5 cm | 2.31 m | ∞ | ∞ | 4.35 m | 0.2% |
| 45 mm | f/3.5 | 6.5 cm | 26.6 cm | 1.72 m | 7.59 m | 29.6 m | 1.3% |
| 45 mm | f/4 | 7.4 cm | 30.4 cm | 1.99 m | 9.03 m | 25.9 m | 1.1% |
| 45 mm | f/8 | 14.8 cm | 61.8 cm | 4.49 m | 37.7 m | 13.0 m | 0.6% |
Handheld & night-sky limits#
NPF assumes typical 20–24 MP sensors (≈6 µm pixels on full frame, ≈3.9 µm on APS-C, ≈3.3 µm on Micro Four Thirds).
| Body | Min. handheld shutter (longest focal) | 500 rule at 15 mm | NPF at 15 mm, f/3.5 |
|---|---|---|---|
| APS-C | 1/60 s | 22 s | 16 s |
| APS-C (Canon) | 1/80 s | 21 s | 16 s |
| Micro Four Thirds | 1/100 s | 17 s | 15 s |

Frequently asked questions#
Is the Canon EF-M 15-45mm f/3.5-6.3 IS STM full frame?
No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.
What is the Canon EF-M 15-45mm f/3.5-6.3 IS STM equivalent to on APS-C?
Its focal length is already the real value for APS-C: 15–45 mm frames like 23–69 mm on full frame.
What is the Canon EF-M 15-45mm f/3.5-6.3 IS STM good for?
As a standard zoom it suits everyday shooting, travel, events and walkaround use.
